Since the Syncbackfree V8.218.0 I become everytime the next errors messages:
\SyncBackFree\SyncBackFree_sel.db-shm
and
\SyncBackFree\SyncBackFree_sel.db-wal
with comment:
Copy of PC: File (2) can not be copied: The system could not find the specified file. The file may have been deleted in the time between scanning and the attempt to copy failed.

Same problem here, SyncBackFree V8.5.43.0. I sincerely hope there a fix in the works for this problem introduced in recent SyncBack updates. I understand that this can be filtered, but we use multiple profiles on multiple computers, and also have several clients that have chosen to use SyncBack and are asking us how to fix this. That is a ton of work to fix something that is a new bug in SyncBack. It is basically a hard-coded and intentional problem that is left up to the users to fix. I do hope the 2BrightSparks folks are paying attention and have plans to hard-code the exclusions for files they create and know in advance are going to be deleted, and thus *always* generate errors. Just sayin'.....
